So, this is a dilemma for me. Like you, painting miniatures (and lately, terrain) is my jam. It's my relaxation hobby, and I love building and using elaborate sets for games. In another era, I'm probably a model railroad guy. So the analog, tangible world of miniatures-based game that I love feels a bit threatened by this.
Because what if it is so good and so easy to use that I just start gravitating towards it? It's...like I'm having a potentially awesome new drug dangled in front of me, but I'm already happy with my plastic addiction. Don't make me choose!
I suspect they are aiming squarely at the same folks who find DDB about as complex as they are willing to go, in terms of virtual experience. i.e. Technologically limited folks like me. Like, I spent a day trying to figure out Roll20 and gave up. Whereas DDB was just easy and intuitive. The new DDB maps feature? I was using it within 2 minutes. Two minutes! Me! That's impressive idiot-proofing.
So I look at something like Foundry and am like, "there is no way I am even trying that." And I think I'm the guy WotC wants to open up their VTT and just sort of click a few times and be good to go.
